New hope for esophageal stricture prevention: A prospective single-center trial on acellular dermal matrix

Figure 1 Operation process of 5/6 periesophageal endoscopic mucosal dissection resection combined with autologous esophageal mucosal transplantation and esophageal covered stent implantation. A: Lugol fluid was sprayed on the whole esophageal mucosa; B: Endoscopic mucosal dissection was performed, and the wound after resection showed an annular mucosal defect; C: The cancerous tissue was removed; D: At the selected normal esophageal mucosa, the mucosa to be transplanted was removed by endoscopic mucosal resection using a polycyclic mucosal resection device; E: A titanium clip was used to secure the excised normal mucosa to the endoscopically peeled mucosal wound; F: The esophageal covered stent was implanted into the compressed transplanted mucosa.
